Description

[Detailed description of the invention] (Industrial application field) Concerning face wash materials.

(Prior art) Many facial cleansers have been provided in the past, but most of these have a basic pH, often foam, cause considerable skin irritation, and cannot be washed off immediately. occupies the majority. Furthermore, in addition to being composed of poor quality surfactants, the ratio of surfactants to moisturizers is often quite high, and the initial roughness and irritation can be exacerbated. It is often heavily scented to compensate for the pleasure.

In contrast, the present invention provides a clear, transparent gel-like facial cleanser. This facial cleanser is made from a skin-friendly non-ionic detergent and is suitable for use on sensitive skin. Additionally, this detergent also acts as a gentle skin wound cleanser. The face cleanser of the present invention also does not require an excessive amount of fragrance,
In addition, it does not form bubbles and can be washed off quickly, and contains an independent moisturizer to keep the skin moist.Furthermore, by using the gel-like facial cleanser of the present invention, the skin becomes even softer. It also prevents peeling and dryness of the skin, resulting in a better balance. Furthermore, the gel-like face cleanser of the present invention is characterized in that the ratio of humectant to detergent or surfactant (humectant: detergent or surfactant) is at least 2:1, and the pH is maintained at neutral. There is. Therefore, it is suitable for daily face washing, and can be applied by lightly massaging with pre-steamed hands.
It can be quickly rinsed off with cold water, and after rinsing, the face can be dried, for example by patting it dry. Additionally, this face wash is especially good for removing makeup;
In this case, for example, apply the face cleanser directly onto a cotton ball, and if necessary, apply the face cleanser again directly onto a clean cotton ball, lightly massage the makeup-covered area, rinse with warm and then cold water, and gently It can be dried by patting it, etc. This face wash also comes in a beautiful clear gel form and is gentle enough for even the most sensitive skin, contains a single skin-friendly detergent and blemish cleanser, and has a neutral rather than basic pH. , contains an independent moisturizing agent, has a ratio of moisturizing agent to surfactant of at least 2:1, is non-foaming, and can be washed off quickly, making this facial cleanser suitable for cosmetic use. It is an excellent facial cleansing material for all purposes, as it is very effective and gentle on the skin.

OBJECT OF THE INVENTION The object of the present invention is to provide a new and improved facial cleansing material, more particularly characterized by a better balance as mentioned above, and which is suitable for cosmetic use and sensitive skin. To provide a new gel-like facial cleansing material that is extremely effective and sufficiently gentle to be used even on sensitive skin.

Another object of the present invention is to contain a skin-friendly non-ionic detergent which also functions as a wound cleanser, which has the above characteristics and advantages, and which does not require fragrance to mask the harsh and undesirable underlying characteristics. To provide a transparent gel-like facial cleansing material that does not cause any irritation.
